Imio.helpers

-----------------

- Be more defensive in `content.get_user_fullname`, in some case, a userid
is found in `mutable_properties` but there is no properties associated with it.
[gbastien]
- Improved `transmogrifier.clean_value` giving a replacement value
[sgeulette]

-----------------

- In `submitFormHelperOnsuccessDefault` JS function, only manage `blob` if
`content-type` is `application/xxx`.
[gbastien]
- Added `content.sort_on_vocab_order` that will sort a list of `values`
respecting a given `vocabulary` terms order. This relies on `sort_by_indexes`
from `imio.pyutils` that is now a dependency.
[gbastien]

-----------------

- Modified `transmogrifier.relative_path` to add option to keep leading slash
(True by default).
[sgeulette]
- In `content.get_user_fullname`, if `fullname` not found at the end,
finally fallback to `portal_membership.getMemberInfo`, this is sometimes
necessary when using LDAP.
[gbastien]
- Removed backward compatible imports for `get_state_infos`, `get_transitions`
and `do_transitions` moved from `content` to `workflow`.
[gbastien]

-----------------

- Added `security.check_zope_admin` (moved from `Products.CPUtils`).
[gbastien]
- Improved `transmogrifier.filter_keys`
[sgeulette]
- Added `workflow.update_role_mappings_for` helper to update WF role mappings
for a given object.
[gbastien]

-----------------

- Monkeypatch `CatalogTool._listAllowedRolesAndUsers` to add `ram.cache` decorator.
[gbastien]

-----------------

- Added `split_text` in transmogrifier module.
[sgeulette]
- Added `workflow.get_leading_transitions` that will return every WF transitions
leading to a given `state_id`.
